T0 a/ZZ whom it may concern:

Be it known that I, GEORGE OULToN, a subject of the Queen of GreatBritain, residing at Liverpool, in the county of Lancaster, in theKingdom of England, have invented certain new and useful Improvements inSoldering-Irons, of which the following is a specification.

Soldering-irons are more commonly made with a solid copper bit attachedby rivets to a metal holder, and are heated by being thrust between thelive coals of a fire. Some are, however, provided with a jet or flame ofgas which,when the tool is held in a particular position, heats thecopper bit. It has always been found necessary when using suchsoldering-irons for the workman to wait while the irons are beingreheated, or to use two or more irons,with the result often that the oneout of use would become overheated and burn before the one in use wascool, and also delay and waste of time occurred. It is to this second orlatter class of soldering-iron that my invention refers; and it consistsin so arranging the bits or head of the iron that one is being heated bythe gas-flame while the other is in use, no loss of time orinconvenience being experienced in changing from the one to the other.It is best described by aid of the accompanying drawings, in which-Figure l is a sectional elevation of a soldering-iron constructedaccording to my invention; Fig. 2, a sectional elevation through thegas-burner; Fig. 3, a perspective view of the head and bits; Eig. 4, adetailed elevation of pipe C, Fig. 5, a sectional plan on line w x.

A is a pipe forming the stem or handle of the implement. Mounted on thisis a handpiece, B, of wood or other non-conducting material. Attached tothe pipe A is a short length of piping, O, of larger diameter,providedwith holes or openings D for the ingress of air.

VThe lower end of this pipe C, as shown in Figs. l and 5, is providedwith a central hole or perforation, through which loosely passes thescrew-threaded stem or neck E, connecting the gas-supply pipe F or itsstop-cock Gwith the pipe H. The lower end of the pipe C is in thismanner embraced between the lower end of pipe H and the upper end ofcock G, as clearly shown in Eig. l, and the pipe O is thereby allowed tobe turned upon the stem or neck E, but not allowed to movelongitudinally thereof.

H is a pipe forming a continuation of the gas-supply pipe F, carrying aburner or outlet tip, I, at the end. The pipe H projects for somedist-ance into the pipe O and beyond the air-holes D, the two formingtogether a burner on the well-known Bunsen principle. The mingled volumeof gas and air passes up the pipe A until it reaches the burner .I atthe other end of the pipe. The burner .I is attached preferably byscrewing to the upper end of the pipe A, and is provided with a seriesof holes, j, round it, through which the mixed gases issue. The burneris provided with a projecting lug, K, at each side, forming aconnecting-piece of T shape, to which the copper bits L are attached,preferably as shown,by an externally-threaded screw on the lug Kentering an internaliy-tlueadcd screw on the bit L.

The construction here shown might, if desired, be altered by making aprojection on the bit L nt orscrewinto the side of the burner J. Thecopper bits may be made of plane surface; but I prefer to make themiiuted at the upper ends, with a series of flutes, Z, as thereby agreater surface is secured upon which the flame will play. Instead ofhaving the connecting-piece or burner J as wide as shown, it might bemade narrower and the two copper bits recessed at the sides whichapproach each other until the end of the ilutings on one touched oralmost touched the other, the flame being made to issue out between theflutings.

V'Vhen in operation, the implement is held with the pipe A horizontal,and with the bit-s L approximating to the perpendicular, the gasesissuing from the holes j in the burner being ignited. The iame risingenvelops whichever of the bits is uppermost. This when heated maybe usedin the operation of soldering, and while in use the other bit as it isturned up,being enveloped in the rising dame, becomes hot and ready foruse as soon as the other one becomes cool, and so on. One bit iscontinually being heated while the other is in use and becoming cool.Thus, in the operation of soldering neither heat nor time are lost.

I prefer to make the implement with two ICO bits, forming with thehandle a T; but-more than two may be used if thought desirable, and bemade to project forward or otherwise placed, so that the rising flamewill envelop one or more while one is in use.

I claim as my invention- 1. In a soldering-iron heated by gas, thecombination of a supply-pipe, a hollow handle, a perforated chamber atthe upper end thereof, and the bits arranged on opposite sides of saidchamber, as and for the purpose set forth.

2. In a soldering-iron heated with a gasjet, the combination,with theburner, of a copper bit having a number of channels at its broader endwhich provide greater surface of metal upon or around which the ame mayimpinge or play.

8. In a soldering apparatus, the combination, with two or more bits, ofa chamber be` tween their bases supplied with gas through the handle andhaving a series of orifices `for gas-jets round the bases of the bits,by which means, when a bit is held vertically upward while another is inuse, the former will be surrounded by and clothed withithe flames of theburning gas.

4. The combination of the burner or connecting-piece J with the twocopper bits L, forming a soldering-iron of T shape to be heated by agas-flame, substantially as described.

5. In asoldering-iron, the combination, with the pipe or handleA,through which the gases are supplied, of the burner J and the copperbits L, substantially as and for the purposes described.

6. In a soldering-iron heated by gas, the combination of the hollowhandle, the bits secured thereto, a supply-pipe, and a connection,substantially such as shown,between the handle and supply-pipe,wherebythe iron may be rotated upon the supplypipe, but not movedlongitudinally thereof.

In testimony whereof I have signed myname to this specification in thepresence of two subscribing witnesses.

GEORGE OULTON.
